Haven't bothered measuring runout as it only appears after a decent turn. I suspect it's more of a dynamic problem. I will be investigating a residual valve, which has been recommended across a few resources I have come across.

[quote]Wilwood does not recommend using DOT 5 fluid in any racing applications. DOT 5 fluid is not hygroscopic, so as moisture enters the system, it is not absorbed by the fluid, and results in beads of moisture moving through the brake line, collecting in the calipers. It is not uncommon to have caliper temperatures exceed 200 degrees F, and at 212 degrees F, this collected moisture will boil causing vapor lock and system failure. Additionally, DOT 5 fluid is highly compressible due to aeration and foaming under normal braking conditions, providing a spongy brake feel.


Understood. When I consider racing the car, I will flush out the DOT5. Until then, I have had no issues with as aggressive of street braking as I can get.
